Holset 4045184 Turbocharger HX35W Assembly

The Holset HX35W model 4045184 is a wastegated turbocharger designed for Cummins B160 and 6BTA160 5.9-liter diesel engines. It utilizes a journal bearing system with wet float oil cooling and features a pneumatic actuator for boost control. The turbine housing incorporates a 12 cm² twin-entry (divided) volute with a T4 flange configuration, optimizing pulse energy for low-end torque response. Compressor wheel inducer diameter ranges between 52 mm and 54 mm, while the turbine wheel inducer measures 70 mm. The compressor outlet diameter is 3 inches (76 mm) and the turbine inlet features a 4-inch (100 mm) diameter T4 divided flange. The wastegate is factory set to approximately 20 psi (1.4 bar) for OEM calibration. This assembly supersedes and interchanges with Holset part numbers 4045877, 4033987H, 3771454, 4049091, and 4047313. Cummins OEM cross-references include 2882034, 4033987, 4035199, and A3960454. It is commonly applied in Dongfeng Cummins heavy-duty trucks and Komatsu PC220 series excavators equipped with the B160 power unit.
